Pin Description
1, 2 Mode Selection (Input) - Determines the operational mode of the device.
3
MCLK Divider (Input) - Setting this pin high places a divide-by-2 circuit in the MCLK path to the
core device circuitry.
4 MUTE (Input) - Engages the internal digital mute and activates the MUTECx pins
5
DIF (Input) - Sets the serial audio interface format. Setting DIF high selects I²S audio format and
low selects LJ audio format.
6 FILT+ (Output) - Full-scale reference voltage for ADC.
7
ADC Common-Mode Voltage (Output) - Filter connections for the ADC internal quiescent refer-
ence voltage.
8 Analog Ground (Input) - Analog ground reference.
9 Analog Power (Input) - Positive power for the internal analog section.
10 Bias Voltage (Output) - Positive reference voltage for the internal DAC.
Mute Control 1 (Output) - Active-low mute output can drive external circuitry to eliminate the
11 clicks and pops associated with any single-rail output. This pin will become a high-impedance out-
put during power-down mode or when an invalid MCLK to LRCK ratio is detected.
Mute Control 2 (Output) - Active-low mute output can drive external circuitry to eliminate the
12 clicks and pops associated with any single-rail output. This pin will become a high-impedance out-
put during power-down mode or when an invalid MCLK to LRCK ratio is detected.
